The mere thought that adults would consider allowing/encouraging children to play violent/misogynistic/inappropriate games seems a madness to me when there are a ton of games out there that are both entertaining and educational and designed to the right age group.
Why not just get your kid some books or magazines to indulge in? Get them puzzles, play monopoly or whatever.....The focus should be on expanding their minds to teach them common sense and life skills, not have them stuck in front of a telly dragging them into the adult world transposing our own maturity upon them
If the game is 15+ or 18+ and you insist on introducing this to your household then make sure your child is of that age....
